Homelessness is when someone does not have a place to live. This could be because they don't have enough money to pay for a place to stay, or because they don't have any family or friends who can give them a place to sleep. Some people can't find a job to earn money to pay for housing, while others may experience health issues or other difficult life situations that make it hard to stay in a home. No matter what the reason, it’s really difficult not to have a safe and warm place to sleep.
